Yes, I've reported 3 servers that were breaking the rules and they instantly made tickets with the server host and the tickets were updated by those hosts within hours. Seemed to work great for me.
Had one character played across 15 different servers over time and all loaded properly. Now every time I join a new server it either resets my character to a brand new one (no deaths involved) or it loads a random one from the 7 different characters I have now. What's going on?
